I would say focus instead on refurbishing old desktops and parts, and teaching poor kids about computers, how to use, troubleshoot, fix and build them, and then they could make use of somewhat older parts, and by adding a decent GPU, could get themselves a basic gaming computer. They would also learn valuable life skills.
My first job I worked at a non profit that was kind of in this sense, but for us the computers were really old (even at the time) but we fixed them up and put Linux on them and donated them.
